L-valine yog ib qho ntawm 20 amino acids siv los ua ke cov protein nyob hauv tib neeg lub cev, uas paub txog tshuaj yog proteinogenic amino acids. Nws yog lub npe rau tsob nroj valerian, los ntawm cov valine no tau ua ntej. Cov DNA codons rau L-valine yog GUA, GUC, GUG thiab GUU. L-valine tsis muaj-ncov qaum thiab yog ib ntawm peb cov proteinogenic amino acids uas muaj ib txoj saw ua ke, nrog rau isoleucine thiab leucine.

L-valine yog ib qho tseem ceeb amino acid, lub ntsiab lus tsis muaj peev xwm yuav tsis pub muaj kabmob nyob rau hauv tib neeg lub cev. Yuav tsum yog li nws tau los ntawm kev noj haus, feem ntau nqaij. Cov khoom noj siv mis nyuj kuj muaj nyob hauv L-valine, tshwj xeeb yog tsev cheese. Cov zaub ntsuab ntawm L-valine suav nrog cov noob taum nplej, nceb, txiv laum huab xeeb thiab taum pauv. Kev siv nyiaj tsawg kawg rau txhua hnub ntawm L-valine yog 10 milligrams ib phaus ntawm lub cev qhov hnyav rau cov txiv neej laus.

Cov nroj tsuag feem ntau ua biosynthesize L-valine los ntawm kev siv pyruvic acid ua ntej ua ntej. Cov txheej txheem ntau kauj ruam no yuav tsum muaj ntau lub enzymes, suav nrog acetolactate synthase, acetohydroxy acid isomeroreductase, dihydroxyacid dehydratase thiab valine aminotransferase. Valine feem ntau tsim ua ke hauv chav kuaj los ntawm brominating isovaleric acid los ntawm valerian extract. Ib pawg amine tuaj yeem ntxiv rau cov txiaj ntsig bromide derivative los tsim valine. Kev lag luam tsim tawm ntawm L-valine feem ntau muaj cov khoom siv los ntawm cov khoom siv carbohydrate.

Kev siv ntawm L-Valine

Kev siv L-valine siv ntau tshaj plaws hauv kev pabcuam kev noj qab haus huv cuam tshuam nws lub luag haujlwm hauv kev ua kom nqaij thiab ua kom zoo nkauj. Kev siv ntxiv ntawm L-valine suav nrog kev tswj hwm kev ntxhov siab, kev loj hlob hauv cov menyuam yaus thiab kev txhawb nqa ntawm lub cev tsis muaj zog.

Cov paib Koj Yuav Tau L-Valine

L-valine yog qhov tseem ceeb amino acid, yog li tus neeg twg uas tsis tau txais nws txaus hauv nws cov zaub mov noj yuav xav tau L-valine pabcuam ntxiv. Cov neeg ncaws pob xws li cov neeg tawm dag zog thiab cov neeg sib tw khiav tawm kuj tseem xav tau L-valine ntxiv vim lawv nquag ua si nyhav. Qhov cim tseem ceeb tshaj plaws ntawm L-valine deficiency yog qhov hnyav poob, tshwj xeeb tshaj yog cov leeg nqaij. Cov xwm txheej ntawm cov hlab hlwb tseem tuaj yeem txhais tau tias L-valine tuaj yeem pab koj vim nws lub luag haujlwm hauv kev tsim cov myelin sheaths uas npog lub hlwb.
